Aldehyde and ketone undergo nucleophilic addition reaction because of polarity between gtC=O group . The reactivity of carbonyl groups toward nucleophile depends upon the nature of inductive effect of froup present at carbonyl carbon. Which of the following is least reactive for nucleophilic addition reaction

Alkyl halides undergo nucleophilic substitution reactions in which halogen atom is replaced by other atom. RX + Nu:^(-) to Nu-R + X^(-) These reactions follow S_(N)1 and S_(N)2 type mechanism, in which S_(N)1 takes place in two steps while S_(N)2 takes place in single step. Due to their tendency to undergo substitution by a large number of nucleophiles, they form a variety of products. Which of the following is least reactive towards S_(N)2 mechanism ?
